Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and apparatus for dynamically managing instruction buffer depths for non-predicted branches, which reduces wasted energy and resources associated with low confidence branch prediction conditions.  <P>SOLUTION: A portion of an instruction buffer for an instruction thread is allocated for storing predicted branch instruction streams, and another portion is allocated to a non-predicted branch instruction stream and may be zero-sized during high prediction confidence conditions. The size of the buffer is adjusted dynamically in conformity with an on-going prediction confidence that provides a measure of how well branch prediction mechanisms are working for a given instruction thread. An alternate instruction fetch address table is maintained so that the instruction stream can be quickly shifted to a non-predicted path when a branch instruction is resolved as a branch to the non-predicted path. This table may be multiplexed with a main fetch address register for addressing the instruction cache.  <P>COPYRIGHT: (C)2009,JPO&INPIT
